To all whom 'it may concern:

Be it known that I, WILLIAM C. SHINN, a

citizen of the United States, residing at Lincoln, inthe county ofLancaster and State of Nebraska, have 'invented certain new and usefullin rovements in Machines for Making Cable Lig itning-Rods3` and l dodeclare-the following to be a full, clear, and exact dcscription of tbeinvention, such as will enable others skilled 'in the art to which itappertaiiis to make and use the same.

This invention relates to im rovements in machines for making cable ligitning rods.

The object of the 'invention is to provide a machine of this characterfor the purpose of a cable, to form a smooth, flexible lightning rodpossessing a maximum amount of surfaceY for the many wires in itsconstruction, thereby greatly increasing the conducting qualities of therods.

With the above and other objects in view,

the invention consists of certain novel fea-. tures' of construction,combination and ar-4 rangement of parts, as will be hereinafterdescribed and claimed.

view of the measuring and registering device carried by the adjustablecable guide pulleys; and Fig. 15 is a detail view, showing the structureol' the cable formed by the n1achine. v l

Referring more particularly to the drawings, 1 denotes the supfportingframe of the. machine, -on one side .o' which isinounted a main 4driveshaft 2, upon which is iixed a drive pulley 3. The driving pulley 3 on`said shaft 2 is connected to a suitable operating mechanism by means ofwhich the machine is driven.

In one end of the machine is arranged an inner eable forming mechanism,consisting of a tubular shaft 4 revolubly -m'ounted in bearings 5 on theparallel cross bars 6 of the frame 1. On the outer end of the shaft 4 ismounted va sproeketwheel which is connected by a sprocket chain.'7 to asprocket wheel S on the end oftheinain drive shaft 2 of AFiXedly-mountedon the shaft 4 and spaced apart at a suitable distance are circularframes 9, between which and journaled in suitable bearings on the outeredges of said frames are radially-disposed wire twisting and spoolcarrying frames 10. Inr

each of the frames 10 are revolubly-mounted a series of wire holdingspools 12, three of which are shown in the present instance as arrangedin each of the frames 10. The journals at the inner ends of the frames1() are tubular, and through said tubular journals are carried the endsof the wires from the spools mounted therein.

j The journals at the opposite ends of the frames 10 project beyond thecircular supporting frame 9, upon which they are mounted, and on theends of said journals .ire fixed gear pinions 13. The pinions 13 areadapted to engage a circular rack or fixed gear 14, which isrigidly-mounted upon a sleeve 15 arranged on the ournal bearing-16 ofthe 'shaft 4.

The wire twisting and spool holding frames 10 are provided on one sidewith tension springs 17, said springs having on their ends suitablefriction blocks 18 adapted tol engage one end of the spools 12 to retardthe movement of the same.

Revolubly-mounted upon a bearing bracket 18 on the end of the frame 2 isa wire holds ing sk ool 19, the wire from which is carried t irough thetubular shaft 4 to form the inner strand or wire a of the cable. ln thesliaft4 adjacent to its inner end is formed a series ofradially-disposed slots 2G, through which the three-ply twisted strandsof-wire l) formed by the wire twisting frames l() carrying the spools 12are passed. The twisted strands of wire b after passing` through theslots20 are wound upon the single inner wire strand from the spool 19 bythe revolving' oit' the shaft 4 in its bearings on the frame of themachine. The wires from the spools 12in the frames 10 are twistedtogether to form the strands f) by the turning of the frames l l) whichare revolved independently of the shaft 4 through the engagement of thegear pinicns 13 on the ends of said frame with the 'fired gear orcircular rack 14 as said frames are carried around by the revolution ofthe shaft 4, as will he understood.

Ther-,ingle wire strand (I. vwhen wrapoof. l. or wound by the three-plystrands e forno; t inner cable for the rod, said inner cable a passingfrom. the end of the tubular shalt 4 engages the outer cable formingmechanism.

. The outer cable forming mechanism consists of a eentrallylisposedtubular shaft 2l, which. is revolubly-mounted in bearings 22 on crossbars 23 of the supporting frame. On. the shaft 21 is mounted apair ofpolygonal bearing frames 24 which are spaced apart and are provided ontheir edges with a series of journal bearings 2.5. In the bearings 25are revolubly-mounted the reduced ends of combined wire'twistingandyspool carrying frames 26, of which there may be any desired number,ten of the same being shown in the present instance. The jour nals atone end of the frames 26 project beyond the adjacent supporting frame 24andl have iXedly-mounod thereon gear pinions 27, which are engaged withand revolved by a large gear wheel 28 fixed on a bearing sleeve 29loosely mounted on the tubular shaft 21. Ori/the opposite end of thesleeve 29 is 'iiXed a sprocket wheel 30. rlhe Isprocket wheel 30 isconnected by a sprocket ohainl to a sprocket wheel 32 on the main driveshaft 2 of the machine, whereby said large gear 28 is revolved, andwhich in turn revolves the gears 27 and the wire twisting frames 26.

In each of the frames 26 is revolublymounted two wire holding spools 33,upon which are wound the wires for forming,r the outer cable. Thejournals of the frames 2G at the opposite ends from the gear wheels 27are tubular, and. through said tubular jonr. nals are passed the wiresfrom the spools 33, said wires being twisted together by the frames 26to form the outer two-ply strands c of the cable. The strands -c afterpassing from the tubular journals of the frames 2G enter slots 34 formedin the end of the tubular shaft 21 and from thence pass throughlthowinding or wrapping die 35 arranged in the end of the shaft 2i. Tfhe die35 consists of a circular block having est/,eraf

formed therein a centrally-disposed aperture or passage 26, throughwhich the inner cable passes, said cable extending through the tubularshaft 2.1 from its forming mechanism, hereinbefore described. The blockor die is alsol provided with an annular serios of apart 37 arrangedaround the aperture 3o, shown. The two-ply ds c after entering through.the slots 34 into the shaft ic through the a ertures i" the die and arewound upon t ie inner cuide hy the 'revolution of the shaft 2iy and dieI35. The shaft 21 is provided on its .ffiosite end with a sprocket wheel38cm;- n ted bye sprocket chain 89 with a sprocket wl. lixedly mountedon the main 2 of the machine, whereby the i; die 35 is revolved. The ed'with tension @necks 42 to enk i e. end of t spools 33 to retard theniovenient of the same.

The cable after being completed by the- 'winding die passes tl'irough aspool/ing or reeling mechanism arranged on the frame 1 and consisting ofa guide pulley 43 revolublymounted in a pulley block 44 having formedtherein a threaded aperture by means of ,which it is adjustablymountedupon a screw-threaded shaft 45 by means of which said block and pulleyare shifted backend forth to evenly guide and feed the cable to a spoolor reel 45. The spool or reel 46 is mounted upon a reel shaft 47journaled in bearings on the frame 1 of the machine.

The screw shaft 45 is eccentricallymounted in bearing disks '48, whichare revo luhly1nounted in hearings 49 on the cross bars 5() of theframe. vided with suitable handles 5l, by means of which they may beturned to move the shaft 45 and to shift the gear pinion 52, which ismounted on one end of the shaft into engagement with one or the other-ofa pair of interineshing driving gears 53, which are mounted onstub-shafts 54 and 55 journaledin suitable bearings on the frame of themachine, thereby changing the direction of rotation of the shaft 45 tocause the latter to move the guide block 44 and pulley 43 back andforth, thus causing the cable to be evenly wound back and forth acrossthe reel or spool 46, as will be readily understood by reference to Fig.8 of the drawings.

'The handles l are rigidly connected to each other by a har as clearlyshown. These handles being thus rigidly connected, the disks 4S in thehearings 4Q are constrained to .move in unison when the pinion 52 isshifted from one to the other of the gears 53. This :auses the bearings48 always to be in alineinent, which alinement is necessary for theproper intermeshing of the gears and smoothness of rotation, on accountof they shortness of the shaft 45sx The disks 48 are proeef/,277

On the shaft 55 of the gear wheel 53 is mounted a sprocket wheel 56,which is con-y mounted thereon a series of changeable leed gears,64. Thegears 64 are of different sizes and are adapted to be engaged by aseries ol driving gears/,65 hXedly-mounted upon a sleeve 66, which-iskeyed to and slidablymounted on a drive-shalt 67 having mounted on oneend sprocket wheel Y 68. The' s )rocket wheel 68 is connected by asprocket c ain 69 to a sprocket wheel 7() on thevinain drive-shaft 2 ofthe machine, whereby motion from saidsha'lt is imparted to the gears 65.The gears 65 are adapted to he shifted into engagement with one or the"other ol the gears 6'4,\thiis providing' for the operation of theshaftgiand tl-ie parts, driven thereby ,at diflerent'speeds. The sleeve60 and the ears are adapted to be shifted by a suitable shifting lever7i, which is slidably-mounted on the frame olf the niachine and isprovided on its inner end with a fork 7 2, which is engaged with anannular groove 73 formed in the adjacent ends ot the sleeves 60, asshown. On the shalt 59 adjacent to the sprocket gear 5.8 is mounted asprocket gear 74, which is Vconnected hy a chain 75 to a sprocket gear76 on the end of the reel shaft 47, whereby the winding` reel shaft 47is revolved to wind the cable thereon. The shaft: 59 is connected by thesprocket chain 61th the changeable speed gear mechanisnn'which providesfor the operation of the reel shalt 47 and reel 46 as well as the feedscrew 45 at the desired speed. The-feed serew`shaft 45 is provided onone end with.a crank handle 77, by means ol which said shaft may herevolved by hand to shift the guideI pulley and block to anydesiredposition.

In order that the cable wound' upon the reel or spool 46 may bemeasured, a suitable ineasuringand registering' mechanism is pro vided.The measuring of the cable is accoinplislied hy forming',r the guidepulley 43 with a circumference of exactly one foot, so that for eachfoot of cable passingr around the pulley the latter will be turned onerevolutioi'i. On one side of the pulley is arranged a tap pet pin 78,which at each complete revolution of the wheel is adapted to he broughtinto engag'ement with the operatiingr mechanism ola registering device,whereby each loot of cable is registlered it is wound upon the reel.

The registering' device, 7S), may be of any suitable construction and isherein shown inY th form ol an ordinary cyclometer, 79, seeu. .ed to thebracket, 44, oll the pulley, 435 and having a tappet wheel, l), arrangedin position to be engaged by vthe tappet pin, on said pulley upon eachrevolution ol the latter, thereby registeringY each loot ol5 cahle woundupon the spool, 46.

From the loreeoine description, takln in connection willi theaccompanying drawings, the construction and operation ol the inventionmay be. readily understood without requirine a more extendedexplanation.
